Letters Patent No. 93,117, dated .Tub/V27, 1869.

IMPROVEMENT IN' LAMIELB'U'RINEIRS.

The Schedulereferred to in these Letters Patent and making part of thesame.

To all whom it may concern: y

Beit known that I, JOHN M. PERKINS, of Cleveland, in the county ofCuyahoga, and State of Ohio, have invented a certain new and`improved'Lamp- Burner; and I do hereby declare that the following is afull and complete description of the same, reference being had to theaccompanying drawings, mak' ing a part of this specification, in which-'Figure 1 is a perspective view.

' Figure 2 is a top view with the capremoved.

Figure 3 is a vertical section.

Like letters of reference refer to like parts in th views.

The naturev of this invention relates-to the construction of alamp-burner, arrangedso that the lampl may be iilled without removingthe burner, it beiug provided with an extensible tube for that purpose,passingdown by the side of the wick-tube, the said llingtube having ,alarge mouth at the `top, and provided with a lid, which, when thrownback, extinguishes the iiame of the wick, and covers the top of thewick-tube.

A represents the body of the burner;

B, the wick-tube; and

C, a filling-tube.

Both these tubes are made telescopic, so that they may be adjustable forfitting various depths of founts.

At the top of the filling-tube O is an enlarged .charnber, B, providedwith a lid, E, covering the same; vthis chamberis designed to facilitatefilling the lamp.

The lid E has a projectionE, and, as will be seen by dotted lines, fig.3, when thrown up, the the said projection covers the top of thewick-tube B.

Bythe side of the wick-tubeB are two small tubes, h and i, one longerthan the other. Thelong one terminates near the top ofthe vwick-tube B.

' These two tubes act as a Siphon, the short one, h, supplying air tothe fount, while the longer one, li, emits the gas to the ame of thewick, the heat of the i llame causing a draught up through the tube i,and

drawing the gas, while air enters and passes down the tube h, to supplythe vacuum.A

By this means a safe and steady light is produiod.

The burner is supplied with wick-wheels, and a cap u for chimney, in theordinary manner.

What I claim asmy improvement, and desire to secure by Letters Batent,is-

l; In a burner, provided with the extensible fillingtube U and wick-tubeB, the tubes h and i, all constructed and arranged to operate as hereindescribed and shown. I i

2. The combination and arrangement of the extensible lling-tube O andwick-tube B with the burner A, as and for the purpose set forth.
